Viewpoint: development status and future direction of router Equipment

With the continuous development of router equipment, I have studied the development of routers under the trend of all ip addresses. Here I will share with you, hoping to help you. The Multi-Service bearer of an IP network has the advantages of uniform protocols and interfaces. It can quickly expand services, simplify network layers, reduce costs of construction, O & M, and business marketing services, and simplify customer relationship management, therefore, a Unified IP bearer network can support larger business economies of scale.

To adapt to this change, the traditional IP bearer network must be changed to achieve the goal of Multi-Service bearer. As the main equipment of the IP network, the security, availability and reliability of router equipment have an important impact on national security, industrial development, and social information construction.

Router devices under the changing trend of IP Networks

In recent years, due to the widespread use of IP networks and the new demands for Multi-Service bearer of IP networks, router equipment has the following new development trends.

High-speed Interfaces

At the beginning of the design, a great role of router equipment is to adapt to high-speed LAN and low-speed Wan. As technology advances, vro devices become the core devices of the IP network. Pay more and more attention to security issues. Network security includes network security, network service provision security, network user information security, and harmful information control. Vro, as the main network device, has a direct relationship with network security, which can also ensure the security of network user information.

Initially, the security of router equipment focuses on the reliability of network equipment, backup of important parts, electrical characteristics of network equipment, and performance indicators of network equipment. With the growth of the Internet scale and technological advances, network security has new requirements for router equipment. At the control level, security should be guaranteed in terms of controlling information access control, controlling information identification, controlling information availability, controlling information non-repudiation, controlling information communication security, and controlling information integrity and privacy. At the management level, the above requirements should be managed to ensure security. On the data plane, security should be ensured in terms of resource availability to ensure that authorized users do not suffer from network unavailability due to network traffic impact. Router devices require increasingly high-speed interfaces to construct a broadband backbone network. Currently, commercial routers have reached 40 Gbit/s, and the lab has already exceeded 100 Gbit/s, which is about to reach the electrical signal processing limit.

Exchange capability tends to quantify and cluster by sea

With the rapid development of information technology, the business carried by the communication network is becoming more and more abundant, especially the rapid growth of IPTV, mobile voice, P2P and other services. Backbone Networks require more and more bandwidth. In the past few years, the growth rate of China's trunk line business volume and bandwidth demand has exceeded 200%, and the annual growth rate is expected to reach about 100% in the next few years. Therefore, the IP backbone network is facing the pressure of frequent upgrades and resizing, and scalability has become an important bottleneck for sustainable development.

The most critical issue in the expansion of the IP backbone network is the expansion of the core router equipment capacity. With the rapid growth of backbone network services, the IP network infrastructure needs to be fully upgraded every two years. operators can no longer bear this frequent network upgrade, there is an urgent need for a new generation of ultra-high-capacity routers for sustainable development. This kind of "sustainability" is mainly reflected in two aspects. First, capacity sustainability: the system capacity can be continuously and smoothly upgraded to meet the operator's business growth needs for a long time in the future. Second, hardware sustainability: there is no need to replace the original equipment for capacity upgrades. All hardware can be used continuously to minimize the impact of upgrades on the business.
